is obtained, with adaptability for adjustment of the securing means to compensate for any form of shank employed and to enable the 1 disk to be positioned at the proper angle and in the proper relationship to the cultivator,

to throw the dirt as the operator may see, fit

and to insure clean and adequate cutting of the trash which it is desired to cut up and to turn under the soil;

To the usual cultivator foot carried by a shank secured to the machine, is connected an lmproved dlsk carrler, means being provided for locking the disk carrler in different positions of angularity in respect to the ordinary the mounting may be adjusted to different angles in relation to the foot and secured in the desired position. The mounting has a tapered thimble and the diskhas attached thereto a stub shaft or gudgeon whose head 39 is riveted to the inner face of the disk and whose shank is mounted in the'thimble, the parts being connected by a bolt running through the gudgeon and having a nut and r washer bearing against the thimble. V

" Thus, the disk is 'mounted so that it will freely turn in the thimble of the disk mounting and the mounting can'be shifted in relation to the foot to dispose the disk at different angles'so that the dirt may be thrown as the operator desires and, in addition, the foot itself can be swung on the usual shovel shank to which it is pivoted and secured a bolt and slot connection 6 by whichit may off attachmentmaybe readily substitutedfor shovels-in anordinary shovel cultivator, V
